From dfeb6d7bfb303c978c51c92cf3d3ea9568402991 Mon Sep 17 00:00:00 2001 From: John Demme Date: Mon, 1 Jul 2024 07:01:08 -0700 Subject: [PATCH 02/27] [ESI Runtime] Incorporate RPC server into ESICppRuntime (#7241) Since the gRPC server is now going to be used in multiple places AND the RPC server now uses ports 'n' stuff from ESICppRuntime, it is appropriate to move RpcServer into ESICppRuntime proper. This also significantly simplifies the build.

Previously we changed to remove prefix since it broke prefixes created in PrefixModules. However https://github.com/llvm/circt/pull/4952 added `prefix` attribute to MemOp so we don't need the workaround anymore. This makes output verilog a lot more LEC friendly. I checked the PR doesn't break prefixes added by PrefixModules on internal designs. --- lib/Dialect/FIRRTL/Transforms/ModuleInliner.cpp | 12 ++++-------- test/Dialect/FIRRTL/inliner.mlir | 8 ++++---- 2 files changed, 8 insertions(+), 12 deletions(-) diff --git a/lib/Dialect/FIRRTL/Transforms/ModuleInliner.cpp b/lib/Dialect/FIRRTL/Transforms/ModuleInliner.cpp index d8e877371a92..99cc874d5466 100644 --- a/lib/Dialect/FIRRTL/Transforms/ModuleInliner.cpp +++ b/lib/Dialect/FIRRTL/Transforms/ModuleInliner.cpp @@ -682,14 +682,10 @@ bool Inliner::rename(StringRef prefix, Operation *op, InliningLevel &il) { if (auto scopeOp = dyn_cast(op)) return updateDebugScope(scopeOp), false; - // Add a prefix to things that has a "name" attribute.
